一种应用于OBS网络的BGP协议设计

Optical Burst Switching (OBS) has attracted considerable research attention from both academic and industrial fields because it perfectly combines high-speed optical transmission/switching technology and flexible electronic processing mechanism. This thesis makes a comprehensive research on BGP (Border Gateway Protocol) and how to use BGP between OBS Ass. The feasibility of using BGP for routing across OBS networks is analyzed. The requirements of BGP for OBS networks are researched and an extended BGP for OBS network is proposed and introduced. This protocol has the main features of BGP and some new route attributes are added. These new route attributes are extended community attribute, available wavelengths, offset time and burst size. Simulation results of the realized BGP for OBS test bed under LINUX operating system are shown.
